Add on the menu loop and clear out the sub-menu variable after each menu
loop.


$tpl = new Template("../templates/");
$tpl->set_file("example", "example.tpl");
$tpl->set_block("example", "MENU", "MENUS");
$tpl->set_block("MENU", "SUB_MENU", "SUB_MENUS");

while ( loop that pulls menu info ) {
    $tpl->set_var(array("NAME_MENU" => $name_menu,
                        "IMG_MENU"  => $img_menu));

    while ( loop that pulls sub-menu info ) {
        $tpl->set_var(array("NAME_SUB_MENU" => $name_sub_menu,
                            "IMG_SUB_MENU"  => $img_sub_menu));

        $tpl->parse("SUB_MENUS", "SUB_MENU", true);
    }

    $tpl->parse("MENUS", "MENU", true);
    $tpl->set_var("SUB_MENUS", "");
}
